Throughout industries from life sciences to electronics, ultra-high decision and precision components are sometimes required for innovation – particularly when that innovation is pushed by miniaturization. As merchandise and know-how get smaller, so do the intricacies of the components which might be the sum of the entire. Many engineers and product designers are turning to 3D printing to fabricate these extremely exact, small-scale components. Additive manufacturing is these days proving to be an environment friendly choice when in comparison with conventional molding.
Micro-3D printing is used to create high-precision tiny components for medical units, optics, photonics, microfluidics, and shopper packaged items. Many of those components have change into the spine of customized healthcare units. They’re additionally utilized broadly in aerospace and automotive.
To get a deeper look into developments in micro-3D printing, we checked in with John Kawola, CEO of International Operations at Boston Micro Fabrication (BMF).
What are some great benefits of micro-scale 3D printing in producing components?
John Kawola: For a few years, creating molds for prototyping was the one answer for micro components, however that methodology was time-consuming and expensive. At the moment, many industries and functions use additive manufacturing as an economical choice for on-demand prototyping and manufacturing, but it surely additionally permits engineers to push the boundaries of innovation.
At BMF, our clients are sometimes searching for a stage of precision that’s merely not possible to attain with conventional manufacturing strategies like machining or molding. BMF’s Projection Micro Stereolithography (PµSL) know-how permits clients to constantly obtain extraordinarily small options with high-precision, decision, and accuracy.

We’ve additionally began to develop end-applications the place we really feel our know-how is uniquely fitted to addressing business ache factors. For instance, UltraThineer veneers – the world’s thinnest beauty dental veneers – wouldn’t be doable to create with out micro-scale 3D printing.
Clarify the necessity for bigger components with the precision and high quality related to micro-scale manufacturing.
John Kawola: Excessive precision isn’t simply necessary for micro-sized components. As product design continues to be a driver of innovation, the demand for extremely exact and correct components stays, no matter half measurement. Whereas BMF is commonly related to micro prints, that are on the core of our enterprise, we will additionally print bigger components with a construct space of 100 x 100 x 75mm. We constructed our microArch S350 platform particularly to handle a market want for individuals who want excessive accuracy and precision, however not on the very excessive decision of our different programs. It’s a 25µm platform that may print at sooner speeds utilizing engineering-grade supplies to allow producers who might not want tremendous excessive decision, however to whom accuracy and precision are necessary.
How has BMF redefined the standard limits of measurement in additive manufacturing? And why was this needed?
John Kawola: Previous to BMF, there have been no choices out there to prototype micro sized components with advanced geometries and small options exterior of conventional manufacturing strategies, akin to micro injection molding. What many corporations discover is that the smaller the half, the more difficult and expensive it’s to fabricate utilizing conventional strategies. Our PμSL know-how leverages mild, customizable optics, a high-quality motion platform and managed processing know-how to provide the business’s most correct and exact high-resolution 3D prints for product improvement, analysis and industrial brief run manufacturing.

At BMF, we offer superior manufacturing options for ultra-high precision functions as a result of we noticed a market want for micro-precision components with dimensional accuracy and precision throughout industries and within the totally different levels of product improvement from prototyping to manufacturing.
What was required to develop automation and speeds wanted for short-run manufacturing of ultra-high-resolution components?
John Kawola: The flexibility to get excessive decision, accuracy and precision with 3D printing relies on a number of components. These embody the decision of the optics, the precision of the mechanical programs within the machine, the management of the publicity and the resultant curing, the interplay between the half and required help buildings, and, lastly, the general measurement of the half and the power to regulate tolerances throughout the construct.
Every of our printers has options that contribute to a step-and-repeat course of that permits for components with excessive decision and managed processing know-how to provide extremely exact objects. The whole microArch assortment additionally features a customizable high-resolution optical system and motion platform, real-time picture monitoring, auto focus and publicity compensation, and operation software program with a streamlined interface and buyer parameter settings. The microArch 3D printing system is ready to understand ultra-high decision, large-area printing that’s utilized in industrial prototyping and short-run manufacturing.
Clarify the refinements in {hardware}, software program, and materials science wanted to perform this.
John Kawola: BMF’s 3D printers use PµSL know-how, which is a type of stereolithography (SLA) that includes a DLP® mild engine, precision optics, movement management, and superior software program. SLA produces components in layers utilizing a photochemical course of. A photosensitive liquid resin is uncovered to mild in order that polymeric cross-linking and solidification happens. With PµSL know-how, a flash of ultraviolet (UV) mild causes the fast photopolymerization of a whole layer of resin.

The PµSL course of we use is prime down. The highest-down scheme not solely minimizes the variety of help buildings required, but additionally supplies a solution to scale back the injury to small options and take away bubbles utilizing a scraper that runs throughout a clear membrane. No helps are wanted to safe the underside floor to the print floor and restricted helps are required for overhangs as a result of interplay of typically mild weight components and buoyancy of the resin. PµSL programs from BMF can obtain XY decision all the way down to 2 µm, minimal function measurement of 10 µm and dimensional tolerance as tight as +/- 10 µm, the know-how helps steady publicity for sooner processing.

John Kawola is CEO for International Operations of Boston Micro Fabrication (BMF). He has greater than twenty years of enterprise management expertise throughout the additive manufacturing, 3D printing and supplies science industries. BMF is concentrated on introducing and scaling micro-3D printing know-how to a spread of industries that demand a excessive stage of decision and precision.
